Aluminium Alloys

Simmal offers a wide range of aluminium alloys. The choice of alloy used in any single application depends greatly on the properties derived from the trace metallic elements present within the alloy.

Care should be taken when considering which alloy to use for your application depending on the properties that will be needed in the end product.

Here are just a few examples of the more commonly specified aluminium alloys.
